Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed February 24, 1915. Serial No. 10,215.

To all whom it may concern Be it known that I, DAVID S. KENNEDY, acitizen of the United States, residing'at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Typographical Machines, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United States No. 436,532, to O. Mergenthaler, wherein circulatingmatrices are released from a magazine in the order in which theircharacters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type characters thereon, and the matrices thereafterelevated and returned through distributing mechanism to the magazinefrom which they started.

More particularly, it relates to that class of machines equipped with aplurality of magazines which are movably arranged so that any selectedone thereof may be brought into operative relation to the assembling anddistributing devices; and its chief object is to provide an improvedform of mechanism for effecting this movement of the magazines, as willbe more fully described in the detailed description to follow, andfinally pointed out in the claims.

In the accompanying drawings, I have shown my invention in preferredform and by way of example, and as applied to a linetype machine, butobviously many changes and variations may be made therein, and in itsmode of application, which will still be comprised within its spirit.Thus, the details thereof may be widely varied and it may be adapted toother forms of typographical machines, such as typesetters, type-castersand the like, which handle type or dies instead of matrices. Generallyspeaking, I desire it to be understood that I do not limit myself to anyspecific form or embodiment, except in so far as such limitations arespecified in the claims.

Referring to the drawings: Figure 1 is a side elevation of a portion ofa linotype machine having my invention applied thereto; Fig. 2 is asimilar view showing the parts in different position; Fig. 3 is a topplan view of the magazine supporting frame; Fig. 4i is a section on theline 4ll of Fig. 1; Fig. 5 is a section on the line 5-5 of Fig. 1; andFigs. 6, 7 and 8 are detail vlews.

The matrices X are stored according to font in the magazines A, B and C,which are carried by the shift frame D. The lower magazine C restsdirectly upon the frame D, while the magazines A and B are mounted upontheir customary base frames A and B respectively, which are pivotallyconnected at their upper ends, as at A and B to upstanding projections Dof the shift frame, and which rest at their lower ends upon theunderlying magazines. The shift frame D is mounted in the supportingframe E, and is arranged so as to be movable toward and from the same tobring one or another of the magazines into operative relation to theassembler entrance G and the channel entrance F, which latter is pivotedto the supporting frame E, as at F and arranged in position to receivethe matrices X as they are released from the distributing mechanism F.The parts so far described are or may be substantially similar to thosedisclosed in my previous Letters Patent No. 1,104,512, dated July 21,1914.

The shift frame D is provided at its forward end with a downwardlyprojecting plate D slidably engaged in a groove 01' guideway E in thesupporting frame E; and at its rear end the frame D is provided withrollers D journaled upon the upstanding arms D and traveling upon tracksE rising from the supporting frame. In this way, the frame D is held inposition upon the supporting frame E and is properly guided in itsshifting movements. The supporting frame E rests at its lower end uponadjusting screws E and at its upper end is pivotally mounted upon a pairof supporting studs E projecting from the framework (see particularlyFig. 5).

As previously stated, my present invention relates chiefly to the meansfor shifting the magazines, and its principal aim is to provide amechanism which is simple in construction, strong and durable incharacter, highly eflicient in operation, and inexpensive inmanufacture. I also propose to which exist in such construction, forexample, the capability of adaptation to ex1st ing machines withoutmaterial change therein, the easy assemblage of the parts, etc. Incarrying out my invention, I employ four rotary cams H, one arranged ateach corner of the magazines, and cooperating with rollers D journaledin arms projecting downwardly from the shift frame D, '(see particularlyFigs. at and The forward pair of cams H is fast upon a transverse rockshaftH mounted to turn in bearings at the front end of the supportingframe E, while the other pair of cams is fast upon a transverse rockshaft H mounted to turn in bear ings at the rear end of the supportingframe.

7 The two shafts are connected by a fore-andaft shaft H which isprovided at its opposite ends with bevel gears H meshing intocomplementary bevel gears H fixed to the two shafts H and H (see Fig.3). By this construction, the two pairs of cams are caused to rotate inunison so as to shift the magazines to equal extents at their oppositeends. Surrounding the shaft H is a powerful torsional spring H? fixed atone end thereto and at its opposite end to the frame E, and tending torotate the cam system to raise the magazines and thus to counterbalancetheir weight.

It will be noted that each of the cams lis formed with two fiat surfacesor steps H upon which the rollers D rest when one or another of the twolower magazines is in operative position, Fig. 2 showing 'by full linesthe steps at the shorter radii of the cams in engagement with therollers, and by dotted lines the steps at the longer radii in engagementtherewith. lVhen the upper magazine is in operative position, the shiftframe D rests upon and is supported by the frame E, as shown in Figs. 1and 5. In order to prevent the overthrow of the cams at the end of theirfull range of movement, one of each pair is provided with a lateral.projecting lug it which is adapted to engage the supporting frame E atsuch time.

The operation of the cam system is effected by a handle J (seeparticularly Fig. 7 fixed to one end of a stub shaft J journaled in thesupporting frame E, and which is provided at its opposite end with asmall gear J meshing into a larger gear K fast upon one end of a shaftK. Similarly the shaft K is provided with a small gear K meshing into alarger gear H on the end of the shaft H of the cam system. Thisarrangement not only enables the operator to shift the magazinesuniformly and with little effort, but the gears are so proportioned asto allow the operating handle to 5 occupy the same position after itsoperation irrespective of the magazine selected, which feature isimportant in effecting the proper cooperation of the handle with lockingmechanism now to be described.

The handle J (see Fig. 7) is provided with a spring-pressed grip Mhaving a de tent M which is adapted to engage in a recess N of a lockingplate N mounted in a block l\ fixed to the'side of the supporting frameE. The block N is formed with a beveled cut N to engage the detent M andpush it outwardly as the handle is rotated so that it may snapautomatically into the recess N when it comes into alinement therewith,and the plate N is formed with a projecting shoulder N to engage thedetent at such time to prevent overthrow of the handle, and thus serveas a locating and registering means therefor. In order to insure that aselected magazine be in proper position, when the handle J is releasedby the attendant, I construct the locking mechanism so that the handlecannot be engaged therewith at any other time. To this end, the lockingplate N (see particularly Figs. 6 and 7 is slidably arranged in theblock N and is connected to an arm N fixed to one end of a short shaft Nwhich carries at its other end a spring-pressed arm N tending normallyto shift the locking-plate N rearwardly, so that its recess N will standout of alinement with the detent M of the grip M. To control thistendency, I

provide the shift frame D with a downwardly extending arm 0 formed withcam projections 0 which are adapted to engage a laterally projecting lugN on the arm N and cause the latter to shift the locking plate N back toits active position. There are as many such cam projections O as thereare magazines in the frame, and they are so located that theywillactuate the arm N only when one or another of the magazines is broughtinto operative position. As a result of this construction, if theoperator fails to complete the operation of the handle J, it cannot'belocked in place (see Fig. 7 but if he does complete its operation, thelocking plate N is shifted to its active position and the detent M willbe arrested by the projecting shoulder N and allowed to snapautomatically into the notch N and thus lock the parts against movement(see Figs. 2 and 6). It may be noted that two complete rotations of thehandle J are required to effect a change from one maga zine to the nextone, so that unless the operator completes both these rotations thelocking plate l 2 will remain in inactive position and the handle cannotbe engaged in its recess.

Referring to Fig. 8, it will be noted that the back plate of theassembler entrance is connected to the usual supporting frame P by anintermediate bracket P ,'which not; only serves as a convenient means ofattachment, but also as a reinforcing device for the assembler entrance.

As previously stated, I have shown my invention merely in preferred formand by way of example, and it is obvious that many modifications andalterations therein, and in its mode of application, will suggestthemselves to those skilled in the art without departure from its scope.
